Management device, management method, and program

Abstract

A management device includes an information acquirer configured to acquire battery information on a usage state of a secondary battery mounted in a vehicle and information on a user from the vehicle, a first feature deriver configured to derive a first feature indicating a state of the secondary battery based on a result obtained by applying the battery information to a battery state detection model that identifies the state of the secondary battery, a second feature deriver configured to derive a second feature indicating characteristics of the user based on the information on the user, and a selector configured to select a battery suitable for the user based on a result obtained by inputting the first feature and the second feature to a matching model that outputs a result showing compatibility between the user and a battery based on the first feature and the second feature.

What is claim is: 
     
       1. A management device comprising:
 an information acquirer configured to acquire battery information on a usage state of a secondary battery mounted in a vehicle and information on a user from the vehicle; 
 a first feature deriver configured to derive a first feature indicating a state of the secondary battery based on a result obtained by applying the battery information to a battery state detection model that identifies the state of the secondary battery; 
 a second feature deriver configured to derive a second feature indicating characteristics of the user based on the information on the user; and 
 a selector configured to select a battery suitable for the user based on a result obtained by inputting the first feature and the second feature to a matching model that outputs a result showing compatibility between the user and a battery based on the first feature and the second feature, 
 wherein the information acquirer acquires a detection value indicating a usage state of the secondary battery as the battery information, and 
 the first feature deriver derives a feature that identifies the state of the battery as the first feature, the first feature being a transition of states being a capacity of the secondary battery, an SOC-OCV curve of the secondary battery, and an internal resistance of the secondary battery in a three-dimensional space model defined by the capacity of the secondary battery, the SOC-OCV curve of the secondary battery, and the internal resistance of the secondary battery. 
 
     
     
       2. The management device according to  claim 1 ,
 wherein the information acquirer acquires vehicle information on a traveling state of the vehicle as the information on the user, and 
 the second feature deriver derives the second feature based on a result obtained by applying the vehicle information to a user characteristic detection model that identifies characteristics of the user. 
 
     
     
       3. The management device according to  claim 1 ,
 wherein the information acquirer acquires information indicating a current, a voltage, and a temperature when the secondary battery is charged or discharged as the detection value. 
 
     
     
       4. A management method comprising:
 by a computer, 
 acquiring battery information on a usage state of a secondary battery mounted in a vehicle and information on a user from the vehicle; 
 deriving a first feature indicating a state of the secondary battery based on a result obtained by applying the battery information to a battery state detection model that identifies the state of the secondary battery; 
 deriving a second feature indicating characteristics of the user based on the information on the user; and 
 selecting a battery suitable for the user based on a result obtained by inputting the first feature and the second feature to a matching model that outputs a result showing compatibility between the user and a battery based on the first feature and the second feature, 
 wherein the acquiring includes acquiring a detection value indicating a usage state of the secondary battery as the battery information, and 
 deriving the first feature includes deriving a feature that identifies the state of the battery as the first feature, the first feature being a transition of states being a capacity of the secondary battery, an SOC-OCV curve of the secondary battery, and an internal resistance of the secondary battery in a three-dimensional space model defined by the capacity of the secondary battery, the SOC-OCV curve of the secondary battery, and the internal resistance of the secondary battery. 
 
     
     
       5. A program which causes a computer to execute:
 acquiring battery information on a usage state of a secondary battery mounted in a vehicle and information on a user from the vehicle; 
 deriving a first feature indicating a state of the secondary battery based on a result obtained by applying the battery information to a battery state detection model that identifies the state of the secondary battery; 
 deriving a second feature indicating characteristics of the user based on the information on the user; and 
 selecting a battery suitable for the user based on a result obtained by inputting the first feature and the second feature to a matching model that outputs a result showing compatibility between the user and a battery based on the first feature and the second feature 
 wherein the acquiring includes acquiring a detection value indicating a usage state of the secondary battery as the battery information, and 
 deriving the first feature includes deriving a feature that identifies the state of the battery as the first feature, the first feature being a transition of states being a capacity of the secondary battery, an SOC-OCV curve of the secondary battery, and an internal resistance of the secondary battery in a three-dimensional space model defined by the capacity of the secondary battery, the SOC-OCV curve of the secondary battery, and the internal resistance of the secondary battery.
